Jesus promised to build His Church on "this Rock", but there is a serious disagreement regarding who he meant by "this Rock". Roman Catholics believe that Jesus was referring to the Apostle Peter. They claim that Christ's statement made Peter the head of Christ's Church and also the first Pope. Baptists, on the other hand believe that Jesus was referring to Himself. This book will examine what the Scriptures have to say about the Apostle Peter and also what they have to tell us about the "Rock."
